Mi3 - Android 6 + Windows 7 Driver Issue

[tybreizh29]

Hi
I had my Mi3 with Android 4.4.4 and Miui 6, now I'm with Android 6.0.1 and Miui 8 (ROM MULTI 6.7.14/15).
Before the update, I had no issue connection my Mi3 to Internet through my PC using my USB port.
After the update the situation is a bit different, I have some issues

• When connecting as MTP or else, whatever I tried, at last Windows 7 x64 says:

• When i try to connect with the RNDIS mode, nothing happends, and the USB selection returns to "Charging".

What am I missing ?
thanks
for your help

Install lates Miflash tool again and all drivers will be up to date (worked for me)

 

[tybreizh29]

I installed
MiFLash_v20160401.zip
and
MiSetup3.2.1.3111_2717.exe

Same issue ...

WIN 7 will install the needed drivers for USB and MTP automatically once thePhone is dedected. Do you hear the system sound if you plug in the phone?

 

[tybreizh29]

sure I ear it.
the phone is a least partially detected because the ADB driver is up and OK.
for the USB and MTP driver, nothing works (windows update find nothing and the install I made also)

with adb.exe command i have this line

unauthorized is not a good device name I guess...

With USB deview (google for it) check all USB devices installed and uninstall not needed, try again if WIN7 starts to install drivers after you reconnect the Phone.
If not you can try an manually install from here (https://androidmtk.com/download-xiaomi-usb-drivers).
Its a bit complicated for me as i have all PC's on Win10.

 

[tybreizh29]

I already have dowloaded that driver at that place.
It made the ADB device working.
But not MTP

 

[fmcheetah]

Try to uninstall all unknown( not wanted) USB drivers and reboot WIN7 to start all over again.
WIN7 is known for driver complications.

 

[tybreizh29]

it always end like this

Try delete MTP from device manager and reboot.

Second USB Device might be empty usb mass storage device for driver installer, that one is not needed. Some official Xiaomi roms has drivers on it.

Something went weird flashing MIUI8
Did you merge the 2 boot partitions to fit MM ?
If not i would recommend to start with clean flash of xiaomi fastboot 6.3.17 rom via miflash. It will make correct partitions.
Then install TWRP and install xiaomi.eu.
Backup your important data in TWRP to USB otg device first.

I did delete the device from dev manager, does the same result after reconnection.

The update of my mi3 has been done using a chineese rom flashed, it has created the correct partitions, then I flashed the xiaomi eu rom. everything has been erased during the process.
I've got TWRP as recovery system, i don't have any more the dual boot.

 

[fmcheetah]

Give it a try and flash 6.3.17 again with Miflash and option flash_all.

 

[tybreizh29]

I just put version 6.7.21
now it works fine
thanks for your help
